Sounds from the outside enter the ambient mics, are processed by the electronics in the PTT module, amplified and/or compressed and routed to speakers in the earpieces. When transmitting, the in-ear mics pick up your voice from inside the ear, and send that to the attached 2-way radio. This system lets you hear everything going on around you while you can communicate via your attached 2-way radio at the same time. The electronics in the ORA TAC limit the volume in your ear to 82 dB, a level that is safe to hear continuously all day. ORA TAC also offers the option of an extra large Big Button actuator for easier use with heavy gloves. Note that the Big Button actuator requires the ORA BASE-BB model which has the necessary jack on the PTT module. ORA TAC requires the correct model of connecting cable to allow connection to your two way radio. To complete your ORA TAC system, you will need the ORA-BASE or ORA-BASE-BB (if you want to attach the optional Big Button actuator) Plus the correct connecting cable for your existing two way radio.
